Loose-LEAF BINDER.

SPECIFICATION forming part of 'Letters Patent No. 730,161, dated J' une 2, 1903.

Application filed October 10, 19702. Serial No. 126,750. (No model.)

T all whom/ it mfc/,y concern:

Be. it known that I, GUsrAv A. ROEDDE, re-

siding at Vancouver, in the Province of Brit- My invention seeks to provide a new and y improved device designed for binding loose leaves or sheets into a book or package form; and it primarily seeks to provide aldevice of v this character of a simple, neat, and 'effective nature, capable of being conveniently applied for binding sheets of commercial or other papers and for permitting a quick separation thereof when so desired.

In its generic nature my invention comprehends a two-part binder, each part having'a member for passingthrough the apertures in the leaf or sheet provided therefor and working one within the other and having means whereby when the two opposing` parts are -]oined together they Will automatically interlock to hold the leaves or sheets firmly in bulk. l

In its more complete nature -my invention includes a pair of clamp members, one ofv which has a socket to receive the other member, said opposing members having combined therewith automatically-interlockin devices, including adetent having an exposed head or finger-piece that projects in a plane beyond one of the presser portions to permit of readily disengaging the interlocking means and to separate thetwo-part binder device in a quick a view of a slightly-modified arrangement of my invention, the telescopic portions `and the presser or clamping members being relatively arranged to project the said telescopic portions over the back of the sheet book-cover. Fig. 3 is a longitudinal section of the parts shown in Fig. 1, taken on the line 3 3 of said Fig. l. Fig. 4. is aview of the preferred construction of my binding device detached from the sheet or leaf book. y Fig. 5 is a view of the two parts separated. Fig. 6 is a vertical section thereof on the line 6 6 of Fig. 5. Fig. 7 'is a detail view of another modification of my invention hereinafter referred to. Fig. 8 is a vertical section of a further modification hereinafter described. Fig. 9 is a detail View of a portion of one of the sheets having the notched end.

In the preferred construction my-improved binder devices are coperatively connected with the. package or book ofsheets in such manner that-only'the presser or clamp members of the two-part binder are exposed, as clearly shown in Fig. l, and insuchapplication of my invention one edge of the book of sheets is suitably cut out or recessed, as at s, for the proper fitting therein of the telescopic body portions ofthe opposing binder members and perforated, as-at s2, for the binding-pins,`said construction or binder devices being a preferred one, forthe reason that in the use thereof only the clamping or presser members and the finger-actuated detent-head of the locking devices appear to view; but I desire it understood I do not limit myself to the peculiar cooperative arrangementiof my binder with the sheet-book, as stated, as the same may be readily varied under my invention, as will `hereinafter more fully appear and be defined in the claims.

In the preferred form of my binder device the two parts designated by A and B are tele- -scopically arranged and have adjustments ings. By reason of the rectangular shape of the body a of the member Av it will be readily understood from Figs. l and S that the same will snugly itthe recessed parts of the leaf-bunch, thereby bringing the outer face a? of the member a flush with the inner edge of leaf-bunch, which serves to steady and hold the body a from loose lateral play, and

the said flat arrangement of the body (L, also provided for fitting said portion a, close up against the outer face oli' the lapped portions C c oi the cover members C C when the binder is used in the manner shown in Fig. 2, the latter arrangement oi' my binder device being employed when it is desired to bind the leaves or sheets without recessing the edges, as shown in Figs. l and 3.

The body Z) of the member B is of a size to telescopically engage the hollow member A, and the said member b in the preferred form is also hollow to accommodate a preferred arrangement of spring-actuated detent mechanism presently again referred to.

The two opposing' binder or clamping portions c b of the parts A and l each have a hie-spindle or receivingpin, the spindle a2 for the member A being in the nature of a sleeve to receive the solid pin b2, projected` from the part D of the member B.

The cover members C C are each provided with an aperture cx cx, in register with the spindle members b2 c2, and in the arrangement of my invention as shown in Fig. l the said cover members are also provided with elongated slots c2 c2, which are in alinement with the recess s' in the sheets S.

So far as described it will be readily apparent in using my binder device in the form shown in Fig. l the body c and the sleeve c? of the part A are pushed up through the slot e2 and the aperture in the bottom cover-section, and after the leaves or sheets are strung Jthereon the upper clamp or binder member B has its body portion l), with the pin b2, slipped through the upper cover-section and brought into telescopic engagement with the hollow body c and the sleeve a2 of the member A, it being manifest that by reason of the adjustability of the part a relatively to the part l) the said parts can be convenientlyand quickly adjusted to suit the thickness of the book of sheets and quickly separate the two to add more sheets` or to separate the said sheets, as may be desired.

To hold the two parts A and B firmly interlocked to the desired adjustments, I provide a simple, effective, and conveniently-operated means ior connecting the said parts and holding them to their clamping positions. In the preferred construction I provide one end of t-he hollow body a of the member A with a series of notches a3, (it being obvious that instead of notches a ratchet-surface may be substituted,) with which the beveled head (Z of a spring latch or detent D engages, the said detent D being mounted within the hollow of the body portieri a of the member A, and the bevel of the head or dog (l is such that in shoving the member I) into the member c it will automatically interlock with the said notches c?. rlhe latch or detent D also includes a finger-actuated trip (Z2, that projects above the upper face of the part a of the member B, whereby by thumb or iinger movement the head d is quickly released from the notches a3 to permit the parts A and B being adjusted or separated, the said member Z1 being suitably slotted, as at Zi", to admit of the proper swing or movement of the latch D, as clearly shown iin Fig. G.

The use oi` the locking element as shown admits ot' an economical construction and also provides for protecting the spring-actuated latch. Furthermore, the form of locking device described permits of using the binder device inside of the cover ends, as shown in Fig. l, and for quickly diseonnecting or assembling the parts A and li to their proper adjustments.

\Vhen the form of binder device so far de scribed is used upon the outside or' the lapped cover edges, the outer or exposed portions oi the members A and B are suitably ornamented, as this arrangement of my invention is especially designed for binding such sheets or valuable papers which do n ot admit of being' cut or mutilated to form the notches'S.

Another and advantageous feature of my invention is that the peculiar cooperative arrangement of the partsAand B and the interlocking devices connected therewith admits of using the entire binding device inside oi' the cover members C C', as shown in Fig. S, by reference to which it will be noticed the covers C C are joined to the members Aand B by rivets c5 c5, and the finger-piece (Z2 only is projected to view-that is, above the covers C.

It is obvious the exact arrangement of the detent devices D di (shown in detail in Fig. G) may be varied. I prefer to use the i'orm shown, however, as it provides for an auto matic interlocking of the detent with the notches ai when pressing the part b into the part rz and also for an easy shifting of the said detent d through the movement oi the member d5 in the direction of the arrow in Fig. (i.

In Fig. 7 is shown a further modification oi my invention. In this form the same general arrangement of parts shown in the other iigures is maintained; but in said arrangement the hollow body of the member A is restricted between its vertical edges to provide a central depressed portion ctx to accommodate a flat spring-detent IO, having a lug l0, which in practice passes through the portion aX to engage with a series oi' apertures bi in the portion bx of the member B and the body b, which in this arrangement is solid.. '.lh e spring-detent lO has its upper end turned out to facilitate the withdrawal of the lockinglug IO.

From the foregoing, taken in connection with the accompanying drawings, it is'believed the advantages and the manner of operating my invention will be readily understood. The assembling of the parts being clear, to separate them it is only necessary to shift the trip member d2 in the direction oi the arrow in Fig. (i, which at once unlocks the two parts and permits the one, B, being pulled up from the other part A, which operation is i`a- ITO i provided in member a2." (See Fig. 3.)

My invention provides a binder complete in itself apart from the'cover, to which it may or may not be attached, as the covers, 'per se, form no part of the'invention and may be omitted entirely, act directly on the leaves or sheets. (SeeFig. 8.) The form of binder shown forms a siin ple, neat, and effective substitute for the more or less complicated, expensive, .conveniently manipulatedV binder d'evices now in general use and especially presents the advantage of being adapted for attachingV to any cover when it is desired to bind the sheets vor leaves within covers.

I am aware that binding devices have been which opposing clamp members having overlapping back pieces are included and which have interlocking` elements.

I therefore claim, and desire to secure by Letters Patent, the following:

1. A binder of the character described, comprising a pair. of hollow opposing members having` clamping portions for engaging the sheets or leaf-pack, one of said members slidable within the other, and locking devices cooperating with the two opposing members for automatically interlocking them in their adjusted position, said devices including an exposed inger-actuated member for the purl poses described.

2. A binder of the class described comprising a pair of separable members, oneof which has a hollow body portion extending the entire width of t-he binder, and a clamping portion projecting at right angles therefrom, and a leaf-penetrating member; the other having a body portion for telescopically engaging the opposing hollow body, a clamping portionV and a penetrating-pin, a spring-actuated locking device for interlocking the two members in their adjusted positions, said device includin g an exposed trip member adapted to be engaged by a finger of the operator for releasing the said two separable members as set forth. y

3. A binder of the class described comprising two opposing separable members, one of which has a hollow body, a clamp portion and as the binder device willv and ina hollow leaf-penetrating sleeve in a plaine parallel with the hollow body,'the other havin g ahollow body portion and a penetrating-pin for telescopically engaging the hollow body and sleeve of the opposing members, and a clampV portion carrying the said penetrating pin; and an automatically-operating device for interlocking the two separate members in their adjusted positions, said device including v a fm ger-trip projecting above the body portion of one of the members for releasing the locking device, substantially as .shown and described.
